Technology doing its job - saving a life

As someone who has nearly drowned twice in their life I really appreciate a computer computer system that can save someone from that fate. That's exactly what the Poseidon system did recently when a girl swimming in a pool blacked out and sank to the bottom under 12 feet of water. Within 3 seconds the system detected her motionless form at the bottom of the pool via video imaging, sounded an alarm at the pool side, and the girl was promptly rescued and resuscitated by a life guard who almost certainly would not have seen her until too late.
